I guided father/son team Ivan and Greg today on the Upper Sac.  We started above Dunsmuir where the water was nice and cool.  In fact, the water was only 50 degrees when I checked it at 11am!  The fishing was a little slow at first, but then we started hooking small and medium-sized wild trout in most of the pockets we fished.  We did well with a brown jimmy legs and a twenty-incher size 12.  The twenty-incher didn't quite live up to its name, unless you count the inches of fish cumulatively.  Both Greg and Ivan got back into the groove of pocket-water fishing after a break of almost 6 years from fishing.  By the end of the day they were short-line nymphing pros.
